The effectiveness of spinal cord stimulation (SCS) as pain‐relieving treatment for failed back surgery syndrome (FBSS) has already been demonstrated. However, potential structural and functional brain alterations resulting from subsensory SCS are less clear. The aim of this study was to test structural volumetric changes in a priori chosen regions of interest related to chronic pain after 1 month and 3 months of high‐frequency SCS in patients with FBSS.

失败的背部手术综合征患者在高频脊髓刺激过程中人脑基于体素的形态学研究。

脊髓刺激（SCS）作为缓解背部手术综合征（FBSS）的疼痛的有效方法已得到证实。但是，由亚感觉SCS引起的潜在的结构和功能性大脑改变尚不清楚。这项研究的目的是在FBSS患者中，在高频SCS的1个月和3个月后，在与慢性疼痛相关的先验选择的感兴趣区域中测试结构体积变化。
